sit st nt-1i mm n in inn sine new in milling part it in mi a TO ALL WHOM IT MAY CONCERN: n v e Be it known that I, AncnIBALD (L CRARY, a resident of the city of Utica, in the State of New York, have invented a new and useful Mode of Heating .Etailroad-Gars, by means of the residuum heat fromthefire in. the furnace .or from the boiler of the locomotive which propels a train of cars.

The nature of my invention consistsin the application or' use of a. second boiler or heater, which may he placed in a horizontal or other convenient position, and so combined with the boiler of the locomotive. as to cause the smoke and heat, which pass from the furnace or the boiler of the locomotive, to pass through the smoke-pipes of this second boiler, and thus to generate steam in the second boiler, for the purpose of heating, the cars attachedto the said locomotive, and in the mode of conveying and ofdistributing the steam for heatini; cars; and I hereby declare that the following is a full, clear, and exact description of the construction "and operation of the some, reference being had to the accompanying drawings, making part of this specification,

infwhich- Figure'lis a perspective view of a smoke-stack or smoke-pipe of a'locomotive, and of the series of steampipes, with their union or coupler, compound joint, and universal joint.

Figure 2 represents a sectional view of the same steam-pipes and the union and universal joint. a i

'Ifhe smoke-stack L has in its lowersection the heater, M, designed to generate steam for the purpose of heating the cars connected with the locomotive. A portion of the smoke-stack'is removed, forth'e exhibition of the upper ends of several steam-pipes, which pass through the second heater or 'boiler. The top of the smoke-stack N is in the aerial form of smoke-s'tncks, thesteam-pipe 0 extending from the said heater above the water which it contains, and passing through the side of the enclosing smoke-stack, extends to the series of horizontaisteam: pipes, through which the steam designed for heating the cars is driven. Nearthe insertion of steam-pipe O is the compound joint A, and immediately back of the joint A isthe cock B, intended to stop the escape of steam when the cars are uncoupled,'and to regulate the-quantity of steam passing intoasaid steam-pipes. The union or coupler, D, near the'said compound joint, is designed to connect flexible steam-pipes with the steam-pipe 0, when metallic-pipes are not used. Pipe C, which is at its front end connected with the compound joint by the union D, is supported at its hind part by 'rest or prop E. This prop is supported by two spiral springs, F F, and is, by said springs, permitted to conform to the motions of the cars, which terminate at the line a b.

The funnel-shaped end of steam-pipe 0, when two-cars are united, in making up a train, receives a steampipe,-,projected from the spherical zone of-the' universal'joint J, and thus forming steam-tight connections, which conform to all the'n'iotions of the cars. .The bracket K is at the termination of the car, and determines the space which the universal joint J shall move forward. The universal jointhT is formed, asshown by fig. 2, by a sphcricalzone,containedina similar zone. These zones arc of such relative diameters as to form a steamti'ght union, and to permit the inner surface of the 'one zoneito move freely over the external surface of the other zone.' .The steamfpipe H is connected withthe largest zone, at its back'end,-and the pipe which slides into the pipe 0 is connected with the front end of the smallest zone, Thesegme'nts cut oil of the spheres, in forming the zones, are regulated in'number of degrees by-the probable deflection of the steam-pipes with which they are connected." Enclosing the steam pipe H -is, the spiral spring G. This spring permits ,the ball-and socket or universal joint J tp be pressed back, ivhen'the cars are to be uncoupled, and thus'allows the pipe G to beraised toa vertical position, and presses the universal joint J firmly against the ends of steam-pipe 0, when the cars are united, and the. steam is being driven into .radiators, and various steam-chambers and steam-pipes placed in each ear for the receipt of steam and the radiation of-heat, The large steam-pipe Ifornis the connec= tion between steam-pipe H and the radiators andsteam-pipes within the cars. p

This series of steam pipes, with its various connections, may be placed above Lor below the passages into the several cars. These steam-pipesmay be united by the universal joints alone, or with the compound joint. The-compound joint being composed of two right-angle joints, admits of the 'vertical and lateral motionsof the crirs. The insertion of, the steam-pipewhich is a continuance of the inner tone, into stetim -pipefqprovides fol the 1atera.l motionsef the carspfor the in stantaneous disruption of a train, and coupling and uncoupling the cers, witlgpu t i nj ury te the steam-pipes} 4 In use of the steam generated by the hedt 5r the steem-Bofler bein'g insfiflieierit' t6 wer m a. trait! of' cars, a woeful steam-pipe; similar. in all'respect s to the pipe may be connected vith the pipe of the boiler of'th'e locomotive, arid. also to steam-pipe), and the escepe-ste'am bc passed-with s'aid pipes, and radiators, in aid of ox= in lieu of the steam of the second boiler.

Having des'c'ri bed my ipvention yhet I claim, is-

,The se p e rate steam-generatr'M on the Iocdniotiveyheatefi' by the \i'a steheat of the smoke or of the exhaust steam,.fo'r-tfie purpose of heat'rhg the train of cars, and constru'cted substantially as herein described.

I also. claim, in 'combiliation with a. separate steam-generator, M, cen structed :is above specified, the use of pipe! 0, H, and I, in the manner as herein set forth and described. I 4 4 I also c1aim,.'in combination with a. separate steam-generator, M, and pipes O,H, and I, as above specified, the use of universal qr compound jqints, in the manner substantially as herein set forth and described.
